Mellencamp Uses Facebook to Kick Bad Habit

John Mellencamp's 14-year-old son has started a social networking campaign on Facebook that he hopes will get his rocker dad to quit smoking.

The 58-year-old Mellencamp has said many times since his 1994 heart attack that he's failed in trying to kick his decades-old habit. Mellencamp's youngest son, Speck, says his dad has promised to quit if he gets 1 million people to join the Facebook group. More than 7,000 people had joined the group as of Tuesday afternoon.
